- Patented Oct. 13, 1931 PATENT? OFFICE JOHN SLSTOKES, OF HUNTINGDON VALLEY PENNSYLVANIA FORMING APPLYING- TAIBBED WRA PPERS TO BOXES original application filed January 8, 1926, Serial No.

I 1930. Serial My invention relates to application of sheets, labels, wrappers, or equivalent, hereinafter generically termed wrappers to boxes, containers, or the like, hereinafter generical- 1 ly called boxes.

In accordance with my invention, reinforcing structures or tabs of paper, cloth, or equivalent'are adhesively secured to a cornercut wrapper of suitable shape or configura- 10 tion and of suitable material, as an inexpensive grade of wrapping paper, in such position as to extend across or bridge the corner cuts or notches, particularly at their apexes, preferably and further in accordance with my invention, the reinforced or tabbed wrapper is coated with adhesive and applied to a box or container before substantial setting or hardening of the adhesive on the tabs and wrapper. I

Further in accordance with my invention,

each corner notch may be bridged by an 1nl dividual tab, or a single tab may have an extent that itbridges two or more cornernotches of the wrapper.

My invention'further resides in the method and products or articles hereinafter described and claimed.

This application is a pending application Serial No. 79,93 January 8, 1926, Patent 1,7 84,317

For an understanding of my method and for an illustration of my products or articles, reference is to be had to the accompanying drawings, wherein:

35 Fig. 1 is a plan view of the wrapper utilized for wrapping a container.

' Fig. 2 is a plan View of a wrapper with reinforced elements adhering thereto.

Fig. 3 is a view corresponding with Fig. 2, showing the wrapper and reinforcing elements in their coated condition.

Figs. 4 to 11, inclusive, are views illustrating steps of a container-wrapping operation when utilizing a wrapper of the character illustrated in Fig. 3. I Fig. 12 is a plan view of a wrapper with individual reinforcing elements for the cor 'ner notches thereof.

In the accompanying drawings and description, the container P is representative of division of my co- 6, filed 79,936. Divided and this application filed March 12 any suitable type of box and container structure and, more particularly, may be of the folded carton type or of the sealed carton type, including the Brightwood. I

Referring to Fig. 1, there is illustrated a wrapper B of suitable material, as paper, notched or out along opposite ends thereof to provide a series of upper end panels, g, g g g and a series of lower end panels, h, 11. and 71 each of said end panels being fold-' able into engagement with the ends of a container as hereinafter described. It will be understood that the size, shape, and number of panels of the wrapper will vary according to the dimensions and type of box or con tainer.

As indicated by the dotted lines in Fig. 1, it may be assumed that wrapper B comprises a tuck-up 2', adapted to be initially secured to a proper part of a container, as the back thereof. Wrapper B may also be assumed to comprise a plurality of similar rectangular sections, j, j 3' and 7' adapted to be secured essentially, to the bottom, front, back, and top of the container in the order named. It is to be understood, however, that the dotted lines described are merely representative of the positions assumed by various parts of the wrapper with respect to the container, and that in practice the wrappers comprise substantially flat sheets, unscored and unlined. l/Vrapper B may also be provided with a printed or lithographic designation of suitable character.

Wrapper B, in each region thereof, where contact is efi'ected with a corner of a container, is formed substantially thicker than in regions more or less substantially removed from it. To this end, wrapper B may be provided with a reinforcing element or elements of suitable material, which may be paper of a weight corresponding with that of Wrapper B or of different weight, as desired. However, since the utilization of reinforcing elements for the corners of the container greatly broadens the range of weight of material that may be utilized for the wrapper, it becomes practical to use a gradeof relatively thin paper for wrapper B.

Along the upper-part of wrapper B, Fig. 2, there is illustrated a cornerand edge-re-= inforcing tab or web carried by the wrapper overlying the apexes of the notches between the end panels g, 9 etc.

Upon completion of the container-wrapping operation, the reinforced tab or web is Will be found to have assumed a position substantially encircling the container at one end thereof, and when carried by the wrapper B in the position thereof, said tab or web Will be ordinarily tucked around into engagement with the adjacent end of the container, the result being that the trihedral corners are strengthened or reinforced.

Along the lower part of wrapper B, Fig. 2 there is shown a tab or web m of the same 0 aracter as the tab structure is, similarly positioned and applied in like manner to the trihedral corner in the wrapping operation inasmuch as a part thereof overlies or bridges the notches between the respective end panels h, 71 etc.

Tabs or webs is or m may be withdrawn from a suitable source of supply, and after one face or surface of each is coated with suitable adhesive, they may be applied to Wrapper B in the desired regions, either by hand or by suitable mechanism. Uponcompletion of this operation, there is effected an application of adhesive to the exposed faces of the tabs or webs 7a and m, and preferably to that face of wrapper B which is to engage or lie a ainst the various sides of the container. .Fhe wrapper thus prepared is shown in Fig. 3 and should preferably be immediately applied to the container, which may be effected in any suitable manner, as by hand or by mechanism heretofore in use for applying non-reinforced wrappers to containers. As described herein, it will be as sumed that engagement between the wrapper and container is efi'ected by the wrapper and container by mechanism of the character noted. is highly desirable that the wrapper be applied to the container before the material hardening or setting of the various adhesive coatings of the reinforced elements and the wrapper.

In Figs. 4 to 11, inclusive, if have illustrated various stages of the wra' ping operation, from the time that contact et ween wrapper B and container P is first efie'ct-ed until completion of the operation.

Having efi'ected inter-engagement of the wrapper and container, tuck-up 'i is folded into engagement with one side cf the container here termed the back, Fig. 5. In so doing, the ends of the reinforcing elements it and m are likewise folded into engagement with the back of container.

Thereafter, as by a simultaneous operation, end panels 72, and g are caused to eng; e, respectively, opposite ends of container while the front side thereof is engaged tially in horizontal teeaaia with section 3' or wrapper B, Fig. 6'. With the container in this position, the corners of the container intersection of the front and top faces lie, respectively, on those portions of the reinforced elements is and m, included in said section j of the wraper B. During the folding of end panels h" and 57 the portions of tabbing structures is and m bridging the panels of the notches between end panels 9 and g and 11. 71, are moved to the position indicated for engagement by panels h and 9 respectively, during the subsequent step or stage.

In the next stage, the top of container P is engaged with section j of wrapper B, and is so doing the corners of saidv container at the intersection of the top and back faces contact with and lie, respectively, on those portions of reinforced elements is and m included in the. section j of wrapper B, Fig. 7.

By the succeeding operation, end panels 9 and It are folded into engagement, respectively, with the ends of the container, portions thereof overlying portions of end panels 9 and h and the exposed portions of tabs 70 and m bridging the notches between the panels.

During this folding operation (Fig. 8), portions of'the tabs 7c and m, bridging the corner notches between panels 72. k and 9 are moved into position for fixing 71 and g and moved into position for engagement by panels 72 and during a subsequent step.

Thereafter, engagement is effected between the back'of container P and section j of wrapper B, Fig. 9, completing the wrapping operation.

In Fig. 12, the wrapper B1 is notched to provide the upper series of turn-in panels a, a a and a and the lower series of turn-in panels 6, b 6 and 6 each of the panels being foldable into engagement with the ends of a box or container as previously described in connection with the application of wrapper B. Along the upper part of the wrapper, there are disposed a plurality of tabs or reinforcing elements e, e and 6 of any desired shape but preferably rectangular, in position to overlie the apeXes of the notches between the wrapper panels a, a etc. A fourth reinforcing element 0 having a shape corresponding generally with that of elements e, 6 and e is carried by wrapper B1 substanalignment with the last named element, the outer edge of element 6 being included in the tuck-up 0. Upon completion of the wrapping operation the steps of which may correspond to Figs. 1 to 11, the reinforcing elements will be found to have assumed a position around each of the four trihedral corners of the container at one end thereof.

Similarly, during the wrapping operation the lower reinforcing elements f, 2 and f are folded or tucked around into engagement with the adjacent end of the container or box whereby they are caused to overlie all three faces of each trihedral corner of the box.

It shall be understood that the reinforcing elements 6, e 7, f etc. may be obtained from a suitable source of supply, as from tapes or rolls, or from previously prepared stacks of individual elements. The elements may be coated with adhesive or glue, as on but one face thereof and applied to the wrapper B1 in the desired region indicated, either by hand or suitable mechanism. Preferably, they are not applied until a period immediately preceding the wrapping operation.

Suitable adhesive or glue is applied to the exposed faces of the various reinforcing elements, as after they are ap lied to the wrapper, and preferably entire y to that face of the wrapper B1 which is to lie against the various sides of the container. The wrapper thus prepared is ready for application to the box, which may be effected in any suitable manner, as by hand, or by mechanism heretofore in use for applying non-reinforced blanks to boxes or containers. It is highly desirable that the wrapper be applied to the container or equivalent before material hardening or setting of the various adhesive coatings that have been applied to the tabs and wrappers.

Although the foregoing description is limited to application to the wrapper of suitable adhesive after the reinforcing elements have been applied thereto, it shallbe understood that this sequence need not necessarily be followed. For example, it is within the scope of my invention to apply adhesive to one face of the wrapper B or 1, and to thereafter apply the desired reinforcing structure or elements in coated or non-coated condition, genorally in accordance with my Patent 1,599,500 granted Se tember 14, 1926, and the wrapper with ta s adhering thereto is applied to a box before setting of the adhesive on the box-engaging faces of the tabs and of the wrapper.
